[SlowE92]

Im at my wits end with this car. I replaced the entire transmission and the shifter, as well as the shifter cable. Whenever i put the car into drive it engages M2. When i put it into sport mode it will show the D/S but will not leave 2nd gear and doesnt shift. I replaced both paddles as well. The car has a jb4 and a Custom MHD BEF for a borgwarner 6973. Im thinking i replaced all hardware then it mist be a software issue but there are no codes. But i occadionally get the transmission malfunction light on the dash so if anyone has any tips or can help i would greatly appreciate it.
